All of a sudden Moo refused to eat his wet food from a dish. He looked at it and walked away. I thought maybe it was the dish so I got him a different dish. He ate from it twice then today he took his paw and pulled the food from the dish with his paw then ate it when it was on the floor. I know he's hungry and likes the food so I don't understand what's going on. Has anyone ever seen this weird behavior?
